Hi. I got myself under 30$ new router product details page https://service.mercurycom.com.cn/product-465-2.html ) and i do not see it under https://openwrt.org/supported_devices section.
Mediatek MT7620DA - main chipset
Realtek RTL8367S - LAN\WAN
Mediatek MT7613BEN - AC WIFI
We also need to know the flash chip model
do you have UART to USB serial adapter?
The original flash is 32 m, has been in 64 m brush TP Archer cc-link C5 v4 normal no 5 g signal
32 mega bits = 4 MB
if you can, open the case and record the model of the flash chip
the flash chip is the black one between the AC WIFI chip and the white antenna wire
it has 4 pins on each side = 8 total pins and labeled U3 on the board
I cannot read it
Have the query to upload
I still cant read it
Probably it is 4 MB and too small for openwrt
This is before, I have change for 8 m can run TP cc-link Archer C5 v4 version of openwrt but no 5 g signal
Oh you changed the flash chip ok
post the kernel log
5 g is no drive MT7613, but TPLINK C5 v4 is MT7612
mt7615 and mt7613 uses same firmware
DEVICE_PACKAGES must have these for MT7613
kmod-mt7615e
kmod-mt7615-firmware
I installed opkg install kmod-mt7615e and kmod-mt7663-firmware-ap no success can't install
and
Does not contain the driver
the packages are
kmod-mt7615e
kmod-mt7663-firmware-ap
do not use opkg install
build a new image with these selected
Where I can't over the wall, unable to compile successfully.
Can be cloned to the source code to compile a firmware contains the driver let me use.
